NA Miata Vent Ring RAM Ball Phone Mount

Ball mount based phone holder for a NA/NB Miata that replaces the factory vent ring. 

The clips that hold the vent ring in place are a little loose in the source model, I opted to not modify them and instead add a spacer via small piece of felt to also help reduce rattling. I'm not a mechanical engineer, so the geometry is made for simplicity not strength optimization.

Requires the use of a 17mm ball mount magnetic phone holder, I purchased mine on Aliexpress.

The volume of the print is quite small so I printed with PETG at 50-100% infill for use with a iPhone 11 Pro. Ideally you would use ASA or similar as this has not been tested in the Texas heat yet.
